To all lwhom it may concern.'

Be it known that I, WALTER L. CONWELL,

residing at Montclair, N. J., and being a; citizen of th'e United States, have inventedA certain new and us'eful Improvements in Metallic Doors, ofy which the followin 'is' aV full, clear, and exact'description, suc as will enable others skilled in the art Jto-Whioh it appertains to make and'to use the saine,`

reference being had'to the' accompany drawings, lwhich illustrate 4thefpreferre form or the invention, -though it is to be understood that the invention is not limited to the exact details of construction' shown and described, as it is obvious that various modi-V fications thereofwill ocourto persons skilled in the art.

In said drawings:

Figure 1 is a side elevation of the doorfy Fig. 2 is a similar view on an enlarged scale, intermediate vertical and horizontal portions being broken out.

Fig. 3 is an enlarged section through'the top rail of the door, taken Online 3 3, of Fig. 1, and looking in the direction of the arrows.

Fig. et is also an enlar ed transverse section, but is taken through the intermediate rail, on line 4 4, of the same figure, and is viewed in the same direction.

Fig. 5 isganother 'enlarged transverse section taken throughthe bottom rail yof the` door on line 5 5, of Fi L 1.

Fig. 6 is a view sim' ar to Fi `3, but is taken on line 6 6,"of Fig. 1, loo ing in the opposite direction. i

Fig. T is a horizontal sectionI through aV portion of the vtop rail of the door and its curtain pocket, being vtaken on line'7 o f VI Fig. 2.

Fig. 8 is another horizontal section and is taken on line 8 8, of Fig. 2, ina lower plane and through one of thestiles; and

Fig. 9 is an end elevation of a portion of the inner edge of the door, showing the applica tion of one of the hinges.

The modern `tendency toward the use of steel and other metals in the architeotural,

car building and other 'structural lindustries has presented among other problems the production of doors Constructed of such ma-v terials, which shall be of comparatively sim-iv ple design, requisite strength, durability andl pleasing appearance, yco

ined ywith all the vmy present -invention,and have had among other objects the ypurpose of providing one of the partsof a door'with a `s'hadepocket adapted to diminish the protrusioii of any` shade or curtainfapplied to the side ofthey door.

Another object is the provision" of copf erating guides for thefree portion of such shade or curtain, and it is Withinvthe comprehension of thel invention to have lsuch guides coact with said lpocket to inclose PATENT oFFiCE.

Patented@ une 1 8, 1918.

either the ends or the entire `rolled portion of the shade, and to vfurnish bearings or bearing attachment means for the shade roller. l

Means for the application of hinges have .been devised which permit of the countersinking of the applied leaves thereof in the manner approved for Well finished doors, and avoid the Y'imposition of inordinate stresses to parts of the door least capable of withstanding them. f

The door edge-outlining and panel-open ing frames, the removable panel and-the means for holdin cushioning and retaining the same, and also the form of the 'comple-l mentary door edge .strips of the door illustrated are, except for the omission of certain typeso-f the latter, similar to the oorresponding parts yof the doors illustrated in an application for sli'dable metallic doors,

iled by me contemporaneously herewith,

.there being, however, lsome new relationships. I v Y y Unenumerated advantages becoming apparent hereinafter obviously With partioular'reference the drawings, l and 2V represent door side sheets on opposite sides of the doorf,prefcrably having i u pp'er'panel openings and being pressed to simulate the Stiles 3ltop rail 4, intermediatel rail 5 and bottom rail 6, of `a` conventional type of door.A The number of panels may be governed by the number of the rails,` and mullions may be introduced in alike manvnei,if desired. Door sheet Zmay haveon'ev come within i the scope of this invention, and are to be re-` gar'ded as so doing, l

panel 7 of sheet 2, and having flanges 8 lapping and Welded or otherwise secured to said integral panel.

Between, spacingl sheet-s 1 and 2 there is, preferably, a door edge-outlining frame comprising channels 9, fitted to each other and having spaced4 outwardly extending shouldered or Z-shaped flanges 9, the outer borders of which are preferably depressed.

Door sheets .1 and 2 former beingsecured, as by Welding, tothe depressed, portions of. lthe flanges 9, of channels 9.v

Parallelingthe bordersof t-heupper panel openings yin said side sheetsl and 2 therey the side sheets and panel-opening frame areivelded, or otherwise united, c

Each ledge of the door, that is to say, each channel 9,7is provided with a finishing strip,

and each ,comprises an external `channel* member 11 and an internal flanged U-shaped channel member 12, both of which may be of equal length, though channel member 12 may comprise short pieces, and the length of the individual finishing strips correspond to the edges of the door-outlining frame to which they are applied.

The outer channel member 11 may be of drawn steel, and the free borders of its flanges are reversely bent inwardly at an acute angle to the remainder of the flanges, and theinternal U-shaped channel member 12 may be a pressing of steel or other metal, and its flanges are outturned and adapted to engage with the internal surfaces of the shoulders ofthe Z-shaped flanges 9a of the channel 9 of the door edge-outlining frame to which it is aiixedf The closed Vportion of each internal U-shaped member 12 is united,

as by Welding-or with countersunk rivets, to the Web portion of the external channel member 11, resolving both channel members.

11 and 12 of each strip into a unitary structure.V

The individual. finishing strips .each has the outturned flanges of its internal channel member 12 lapping the :transverse portions of the Z-shaped flanges 9a of its associated channel 9, the outer edges of said flanges andthe door-bounding flanges 1a of side sheets 1 and 2 abut the. web of the external channel member 11, and the.. deflected portions of the flanges of this member bear and bounding side Y also each havebounding flanges 1a and contiguous shoulders, the,

against the said flanges of the side sheets 1 and 2 and the shoulders forming the outer edge ofthe stiles 3. n

The finishingstripsarefcapable of endu'ise application to their respective channel members 9, and of longitudinal sliding movement therewith, having also ay friction-` producing fit with said channels.

Each finishingstrip is arranged to have vits ends so overlap the ends of adjacent finishing strips that, after-@beingpushed/into their Vnormal positions, said; finishingv strips interlock with yeach, otheu` and becomeselfretaining. 4This interlocking of the finishing, stnips, howeven, forms. subj ect-matter of another applicatioiifiledby ine on an even date` herewith and entitledl 4hletallic Ydoor With' interlocking i p arts.;

p At suitable locations the `channel 9, yof the hinged end of the. door, and the finishing.

striptherefor are cuty away for the application, ofV hinges-` Within the zone iof the cutaway portions, and ypreferably co-eXtensiveivith-the length.y thereof, is inserteda reinforcement 13, ,best shown in Figs2 and 8. The cross section of .each reinforcement.

is shown as substantially T-shaped,=its.steni bearing against the inner .Wall of channel 9 andy being thickenoughto fill the spaceibetween What remains of theZ-shaped. flanges Vof said channel,y z'. e., the transverse portions of the channel flanges.

The cross `legvof .the T-shaped reinforcementV bears againstxthe shoulders of` side sheetsl and 2, and its outer surface is inset from the outer surface of outer channel meinberll of 1the laffiliated finishing strip.

Secured by screws 141 to the outer facefof thev cross. leg' ,ofV reinforcement 13is oneY leaf of a hinge 15. Saidcrosslegof the reinforce ment is. preferably.v thick Aenough to `causethe outer faceof thehinge leaf. todae in .the same plane as the outer face of-channel. member 11 ofl the finishingstrip.

Referringc-to thel upper panel-opening,-ia

molding frame is provided.therefor:com-` prising suitable.. pressed or otherwise formed strips l'ttedoneto the other. Preferably, eachstrip rcomprises ay pair. of .parallel flanges adapted to lap the panel-opening outlining flanges of. side .sheets 1 and 2,. a

molding. contour portion, either,.,beveled or l partaking of thelines `of a .classical molding,

andan opening;surrounding depression adapted to receivea glass or otherremovable panel 17 'and cushioning'strips ,1S.

Said! retaining strips 19 may be secured, as shown,

by screws 20, which pass-through saidr retaining strips 19, flangesof moldin strlps 16 lan panel-'opening.'frame. O vIt necessary to insert lthe screws only from fone side ofthe panel. v

Molding strips` 16 are 'j shown mitered, and while not necessary, it is desir'f able to weld their joints transversely except for' a transverse distance ual approximately to the width ofthe taining lstrips 19. By leaving these latter flanges ununited, they maybe bent to facilitate the assembhng of the molding frame. y It is well known that, l"when applied'to doors, shades or curtains lare-mounted 'to bepulled' downwardly I in some instances and upwardly in others, relatively narrow. double doors 'of street cars, crosswise of the door. Therefore, it immaterial which railfor stile is selectedY for the applicationof most'common location-the Atop ra1l' 4 'ofthedoor.y u Y i" Simulated top rail r4 ofl side sheet 1 is provided Ywith a recta lar opening 21, advantageously having a engtli the width of the upper removab e panel 17, and any suitable heightJWi'thin top rail 4, which is hollow, and positioned to form a horizontally disposed concave wall isa curved sheet 22, havin the curvature'of a cylindrical segment.' aid sheet 22 is supplied with upper and lower horizontal flanges, arranged to lap the borders of the 21 of side sheetl and adapted to openin be wel ed or otherwise secured' thereto."

Closing theopenings at the opposite ends of the' concave sheet-22, are endpieces 23 of angular horizontal section, avertical flan e'. Vof each of which may be welded to thea jacent vertical border of opening 21 inside sheet 1. YA pocket iswthussiformed in. onevv side of the door for the partial reception of a shade roller and the rolled portion of the curtain or shade.

A pair of combined shade bracket andy guide members are arranged one on each side of the removable anel`17, and each is preferably constructed) shown in Figs. 7 and 8, these' parts preferably being fused togethen' The cross section through the guide rtion is revealed in Fig. 8, where the insi e strip 24 has a zig-,` zag or step edy section, and the outer strip 25 has .ar shaped cross section, the Vforward inwardly-projecting flange 26 of strip 25 being rebent upon itself to abut'the forwardly-extending flange 27 offtthe inside strip 24. The rear flange 28"of the: outer VZ-shaped strip y25,y projects outwardly'y andV those ofsheety 1 whchoutline the panel-opening in said` sheet, and through vflanges of channel membersfl forming 'thea curtain roller.
